  • Process for preparing trialkylammonium dihydrogen phosphates
    Patent number: 11932588
    Abstract: The disclosure provides a process for preparing solid tri(C1-C4 alkyl)ammonium dihydrogen phosphates such as triethylammonium dihydrogen phosphate, in high yield, and in a free-flowing particulate form. The solid product advantageously possesses less than about 1500 ppm of aprotic organic solvents, less than about 1500 ppm of C1-C5 alkanols, and less than about 500 ppm of water, as determined by Karl Fischer titration.
    Type: Grant
    Filed: November 10, 2022
    Date of Patent: March 19, 2024
    Assignee: ENTEGRIS, INC.
    Inventors: Jonathan W. Dube, Christopher Brown, Keith Hao-Kiet Huynh, Hitendra Patel
  • Method for preparing iodosilanes
    Patent number: 11905174
    Abstract: Provided is methodology for the preparation of highly-desired iodosilanes such as H2SiI2 and HSi3, via a reaction of alkylaminosilanes with certain substituted acid iodides. In one embodiment, bis(diethylamino)silane is reacted with benzoyl iodide to provide diiodosilane.
    Type: Grant
